Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Still early. Manus is more flexible for less money.
